To all whom it may concern Be it known that I, DANIEL Mnncmn, citizen ofthe Republic of France, residing at 3 Rue Basse Ste. Claire, Annonay, Andeche, in the Republic of France, have invented new and usefulImprovements in Machines for Stretching Hides of which the following isa speciof the hide.

The present application is a division of my co-pending application forpatent, Serial Number 789,222, filed September 11th, 1913.

In the annexed drawing given by way of example: Figure 1 is a View,partly in section, of the improved drum for treating the edges of thehide. Figs. 2, 3 and 4 are enlarged details of the blades mounted onsaid drum, Figs. 3 and 4 being cross sections along the lines A-A andBB, respectively, of Fig. 2.

The stretching drum 1 the hide is of a generally and keyedconcentrically on its shaft 2* which is rotated by any suitable means.The blades 11 secured on its periphery are arranged radially. Their edgehas a slight convexity from one end to the other and is provided withrounded notches 12 spaced by solid parts 13. The edges of the bladeshave a rectangular cross section in the parts 13 as shown in Fig. 3,section in the notches rounded parts progressively into the rectangularparts so as to form no for the edges of cylindrical shape 12 (Fig. 4:).The

The blades are preferably so arranged that thenotches 12 in one blade are in alinement with the solid parts 13 of thenext succeed- The hide to be dressed is held on the periphery of thedrum by means of a brush, a leather band, or the like. The drum soconstructed permits of finishing the dressing of the hide in a veryefiicient manner, by drawing and softening the edges in all directionswhile exerting a slight scraping effect.

Having now described my what I claim as new and desire to Letters Patentis:

1. In a machine for stretching hides and skins, the combination of ashaft, a stretching drum carried on said shaft, blades secured radiallyon the periphery of said drum, said blades being provided with notchesthe edge of each blade being rounded in the notches and square in thespaces between the notches, substantially as described and for thepurpose set forth.

2. In a machine for stretching hides and skins the combination of ashaft, a stretching drum, carried on said shaft; blades secured radiallyon the periphery of said drum, said blades having a curved edge from endto end and being provided with notches, the edge of each blade beingrounded in the notches and square in the invention, secure by spacesbetween the notches, substantially as described and for the purpose setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
